These few monthes weren't easy for you. You lost everything because of a mission. Nothing could hurt you this badly, but.. except anything else you could lose, you lost your brother, and it made you crazy. Your friends, the avengers, tried to help but they weren't able, even the therapist wasn't able to help. You go to base, get the missions, do them seccessfully, and get back home like nothing happened. But it's not like always and it's obvious for anyone, you act like a crazy person, kill people at missions ruthless, avoid to talk to the others, don't care about anything and always have lots of scars and stitches. You got many nerve tics, and can't even control them. You seem don't want anyone to help you, but everyone knows you're just hurting yourself.
